寻网页中JS实现的图片切换特效

小桔灯这个页面是用Flash实现的，但我不想用Flash，只希望用 JS + CSS + HTML 实现。 展开

我修改测试通过一个。但是有个问题。若改成鼠标悬停边缘滚下去，也就是onMouseOver。是停不下来的，会一直滚下去，因为无论怎么样都是鼠标碰触事件。所以我强烈建议用点击事件,onclick。
js css image都是调用的。我都写到页面里了，你自己改下。图片地址我没改。本地测试的。自己换成你的图片。

要实现页面的图片的轮换的效果其实很简单 首先你需要在body里面插入一张图片 然后通过js获得id 在通过图片的 src 属性来实现 ，如果你不明可以接着提问，我将把代码写给你

试试这个图片切换
有12345数字一起切换
鼠标点一下数字会变换到另一张图片，不点就会自动换
里面有教程和源码
追问
不要这样的，这样的我自己会。
这样的效果在许多网站被应用，看得多了觉得没什么美感了。
还是我说的那个效果，比较满意吧。有点像 Mac OS X 中Dock的效果（只是有些像，但 Dock 没有自动滚动效果）。
